sns PATENT car ca- UPHOLSTERING SPRING STRUCTURE.

Application filed January 11', 1915. Serial No. 1,525.

Another object of my invention is to produce a structure that willprevent noise, due to contact of adjacent springs and to cheapen thecost of manufacture Without decreasing the durability and efficiency ofsuch devices.

Other and further objects of my invention will become readily apparent,to persons skilled in the art, from a consideration of the followingdescription when taken in conjunction with the drawings wherein:

Figure l is a plan view of a fragment of my improved structure showingparts of the top cover removed, and some of the springs taken from thelower cover. Fig. 2 is an enlarged transverse section taken on line 22of Fig. 1. Fig. 3 is an enlarged fragment of a modification.

In all of the views the same reference characters are employed toindicate similar parts.

In carrying myinvention into effect I provide a fabric top and bottom,and in each I form rows of spring receiving and retain ing receptacles,preferably quadrilateral in form, for receiving the terminal rings orconvolutions of upholstering springs, preferably of the hour-glass type,at regular spaced apart intervals, said springs being separated byintegral laterally projecting parts of the fabric, such as seams, welts,or the like, each spring-receiving space inclosed on all sides by theselaterally projecting substantially continuous separating means, beingcrossed in opposite directions by cords, under which and between theseams the terminal convolutions of the springs are subsequently passed,in the respective covers, thereby physically separating the springs, onefrom the other, to prevent noise by contact of the springs, and

thus providing a most excellent means for retaining the ends of thesprings in uniform positions, with respect toeach other.

In the drawings, exemplifying one form which my invention may take, 10is the lower cover, consisting of a relatively coarse fabric, preferablyburlap, or the like, to which the end ring 11 of each of theupholstering springs 11-11 is connected, and 12 is a similar top coverof burlap, to which the other the end rings 11 of all of the, springs v1111 are in like manner connected, and

held spaced apart by .both covers without permitting contact at anypoint, of the respeotive springs with each other. A series of parallelseams or welts 1313are made across the top and bottom 10 and 12,respectively. The seams 1313 are separated about the same distance apartas the diameter of'the largest convolution of the springs 11, so thatthe springs 1111 can be comfortably seated between the seams 1313.Similar, angularly disposed seams 14'14 are made substantially the samedistances apart, with respect to each other and are 'formed in the topand bottom covers at preferably right angles to the seams 1313, therebyforming quadrilateral recesses with-' in which to receive the ends ofthe springs.

The seams 13 and 14 project laterally distances from the face of thefabric greater than the thickness of the wires forming the endconvolutions of the springs and through the seams cords 1515 are carriedtransversely across the seams 1313 and substantially mid-way betweenadjoining seams 1414 in the top and bottom covers and in likemannercords 16-16 are passed transversely across the seams 14L14t and midwaybetween the seams 13-13. The cords 15-15 and 1616 cross each other inthe center -of the quadrilateral space encompassed by the seams '1313and 14t-14:. Instead of making seams only, as shown in Figs. 1 and 2, Imay provide welts as shown at 13 in Fig. 3, to make a "strongerstructure. The fabric at 13 surrounds a cord 18 forming a welt, toprovide stronger and stiffer means for holding the cords 15 in place.After the top and bottom covers, 10 and 12, have been made, in themanner described, the terminal convolutions or rings of. the springs1111 are slipped in under the crossing cords 15 and 16 and betweenadjacent seams 1313 and 1414 of each of the spaces, the points Where thecords cross will then be in planes of the longitudinal axes of' thesprings. After the terminal ends of the springs have been passed intothe receptacles of one of the covers, say the bottom, the top cover isthen laid over the assembled springs and the upper ends of the springsare successively passed between the fabric and the crossing cords, intothe receptacles in the top cover as clearlyshown in Figs 1 and 2, andthe covers 10 and 12 then are sewed together, as at 19 at their marginaledges thus inclosing the springs.

may or may not use a wire, margin frame 20, around which the top andbottom covers 10 and 12 may be stitched, as shown in Fig. 2; For someconstructions the margin frame 20 would be of some ,advantage and inothers it would not be required, but when it is used, it may be securedto the covers at the selvage edges of the assembled springs and thefabric may be made to cover it in the manner shown. When the terminalends of the springs. 11 have been placed under the erossing cords 15 and16, the sur rounding seams or welts 13 and 14 will prevent them frommoving laterally and the cords will prevent them from moving vertically.They will therefore be retained in the positions in which they have thusbeen placed with the yieldable fabric, preferable that of the covers,interposed between ad-' joining springs so that there can be no metalliccontact between any two springs and therefore the structure ispractically noiseless when in use.

The top and bottom fabrics 10 and 12 are reinforced, by the scams orwelts: as where the respective seams or welts intersect or cross eachother between adjacent springs, without increasing the rigidity of saidcovers to any appreciable extent.

While I have herein shown a single embodiment of my invention for thepurpose of clear disclosure it is evident that changes may be made inthe general form and disposition of the parts within the spirit andscope of the appended claims.

Having described my invention, what I claim is 1. A structure of thecharacter described menses tirely inclose the springs.

2. A structure of the character described comprising a top and bottomfabriccover,

each having integral, laterally-extending substantially continuousprojections angularly related by intersecting each other at suitableintervals to provide receptacles to receive the end rings of coilsprings; a series,

of coil springs, having their end rings within said receptacles of therespective top and bottom covers; cords, parallel with and betweenadjacent projections of a series and passing transversely through theprojections of the ,angularly related series, said cords crossing eachother within each spring receiving receptacle and overlying the endrings of the respective springs.

3. A structure of the character described comprising a top and bottomfabric cover, each having two series of integral, laterally extendingsubstantially continuous projecting seams, angularly related byintersecting each other at suitable intervals to provide a series ofrows of receptacles, to receive the end rings of coil springs; a seriesof rows of coil springs havin their end rings within said receptacles ofthe respective top and bottom covers;.cords parallel with and betweenadjacent seams of a series and passing transversely through seams of theangularly related seriesysaid cords crossing each other midway over eachspring receiving receptacle and overlying the end rings of therespective springs.

In testimony whereof I hereunto set my hand in the presence of twosubscribing witnesses.
